How to generate a sprite from images with repeat-x or repeat-y using Gulp and Spritesmith?

Question

css

Hello! Tell me, is there any way to automate image stretching with repeat in Spritesmith ?
That is, let's say there is a file called header-repeatx and, depending on the name, the image in the sprite is automatically stretched to the full width (repeat-x) or the full height (repeat-y) of the sprite. Is this possible in principle or will these images have to be stored separately from the sprite?
